CLASSIFICATION: E80T5-B2LC per AWS A5.29, ASME SFA 5.29

Select 85-B2L is designed for single and multiple pass welding of certain chromium- molybdenum steels, plate and pipe requiring 1¼ % chromium and ½ % molybdenum in the weld deposit.

APPLICATIONS: Select 85-B2L is a good choice for welding thin-walled A335-P11 pipe and A213-T11 or A213-T22 tube in the as-welded condition or in applications where low hardness is required. The basic slag imparts better CVN toughness than rutile slag electrodes when welding these steels, which are used in the construction of boilers, heat exchangers and pressure vessels.

DIAMETERS: .052", 1/16”, 5/64”, 3/32”

SHIELDING GAS: 100% CO2, 35-50 cfh

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Excellent mechanical properties with basic slag.
  • Low weld metal hydrogen.
